bolted to the floor. Between the upper parts of said plates 2 2 extendsa rear shaft 5, having fast upon itself saws 6,which are statione atsuitable intervals to cut the macaroni into such lengths as may bedesired. Said saws 6 To all whom it may concern.-

Be it known that I, SAMUEL MUELLER, a citizen of the United States,residing at Jersey City, in the county of Hudson and State have inventedcertain new 5 of New Jersey,

and useful Improvements in Macaroni-Saware each inclosed in a casing 7,which is open ing Machines; and I do hereby declare the at its frontside, as at 8, to provide access to following to be a full, clear, andexact dethe macaroni an at the rear has a tubular scription of theinvention, such as will enable extension 9, which is connected with anyorothers skilled in the art to which it apperdinary style of blower (notshown) to draw tains to make and use the same, reference be or carryaway the sawdust which arises from ing had to the accompanying drawings,and the cutting of the macaroni. Forward of the to numerals of referencemarked thereon, rear shaft 5 is arranged a second shaft 10, which form apart of this specification. also having bearings at its ends in the saidThe objects of this invention are to proplates or frames 2 2. Upon thisshaft close vide a machine for sawing macaroni into suitto one of theside plates 2 is arranged a transable lengths for packing, to thusenable the verse plate or stop 11, against which the ends strips ofmacaroni to be cut into lengths meof the macaroni to be sawed may abutto 'se chanically and with greater accuracy than cure their being even,said stop being located can be attained in cutting them by hand, to at asuitable distance from the saws 6. Said enable a large number ofmacaroni sticks to saws are preferably adjustable lengthwise of be cutat one time, to secure a rigid holding the shaft 5, so that the samemachine can be of the macaroni during said cutting, to ob adjusted toout different lengths. The shaft tain a machine which shall perform thecut- 10, furthermore, carries at suitable points ting rapidly and withlittle attention upon circular series of radially-projecting arms 12,the part of the operator, to enable the cutting which are adapted tograsp and hold the bunto be done with less care and skill than handdleof macaroni being sawed. In the drawwork re uires, and thus reduce thelabor and ings I have shown one circle of holding-arms cost, and toobtain other advantages and readjacent to the stop-plate 11 and twoothers, sults, some of which may be hereinafter reone on each side oftne first saw and a fourth ferred to in connection with the descriptioni at the inner side of the second saw, the short of the working parts.ends which are severed by said second saw The invention consists in theimproved being drawn away with the sawdust by the macaroni-sawingmachine and in the arrangeblower. ments and combinations of parts of thesame, Each of the holdingarms 12 comprises all substantially as will behereinafter set halves 13 14, adapted to be bolted together, forth andfinally embraced in the clauses of as at 15. (See Figs. 3 and 4particularly.) the claim. Preferably a series of the arms 12 is arrangeReferring to the accompanying drawings, around the shaft .10, so that aplurality of in whicn like reference-numbers indicate corbunches ofmacaroni may be inserted at each responding parts in each of the severalfigrevolution of the shaft 10. Obviously the ures, Figure 1 is across-sectional view of a number of arms thus employed in a seriesmachine of my improved construction. Fig. will be limited only by thespeed of rotation 2 is a front elevation of the same. Figs. 3 and thedexterity with which the operator and 4 are detailsin side elevation andplan, can insert the macaroni. I have shown in respectively, of one ofthe holding-arms; and the drawings four such arms 12 in a circular Fig.5 illustrates the driving connections of series, and in this case theupper part 14 of the machine located at the end of the same. one arm ispreferably cast in one piece with In said drawings, 2 2 indicate endframes the under part 13 of the next arm, so that all or plates of myimproved machine, which the arms together completely encircle the boltedtogether clamp shaft and by being as shown in the drawthemselvesthereon, ings.

are adapted to support between themselves the shafts and working partshereinafter described, said end plates or frames 2 being held inrelative parallel positions by means said plates 2 providing l wardlyand forwardly concavely curved exbottorns feet 4 to stand upon or be attheir I tension 16, upon which as the arm is brought The under part 13of each arm has a down-' ITO upward by the revolution of the shaft thebundle of macaroni sticks is adapted to be laid. The upper member 14 hasan oppositely-curved extension 17, which projects, however, onlypartially as far as the firstmentioned extension 16, so as to leavebetween the ends of said extensions 16 17 an opening 18, through whichthe sticks of macaroni may be inserted. The holdingarms 12, it will beunderstood, are sufficiently broad to form a suitable seat for thesticks of macaroni.

To close the opening 18 of a holding-arm and to bind the macaroni inplace while being sawed, I have provided upon the extremity of the upperarm extension 17 a hinged gate 19, which is adapted to close across theopening 18, passing at its extremity along the inner surface of theextension 16 of the under member 13 of the arm and closely adjacentthereto. This gate can close inward macaroni and thus it adapts itselfto any size of bundle, always grasping in an equally effective manner.means for automatically opening the gate 19 as the arm comes intoposition to receive the macaroni and for again closing the same tightlyagainst the sticks as they pass away from the operator to the saw. Forthis purpose I have shown in the drawings a leverarm 21, pivoted uponthe base of the said gate 19, as at 22. The inner end of this lever-armforms a V-shaped lug 24, engaging the back of the gate 19 when said gateis open I and preventing the lever-arm 21 from being forced back by thepower of springs 26 23 into another than perpendicular relation to saidgate. (1 spring 23, being bent around the pivot-pin 22, is fastened toleverarm 21 at one end, at the opposite end engaging the outer extremityof the gate 19. A spiral spring 26 extends from the said leverarm 21 tosome part of the mechanism which is fixed with reference to theholding-arm as a whole, preferably the body portion of the nextholding-arm, as shown in the drawings. The effect of this spiral spring26 is therefore the opening of the gate 19, and between which is pivotedthe lever-arm 21. As will be understood, and furthermore, a detentleaf-spring 28 may be provided upon the arm member 14orits extension andcurved at its extremity 29 to snap over a shoulder 30 of the gate 19.For forcing said gate 19 shut after the macaroni has been inserted aroller 31 is held in position to engage the outer end of the gate 19 asthe same projects out, tending to close said gate and throwing the outerend of the leverarm 21 upward between said roller 31 and the end 33 of acurved track 34, which extends .saws or at the lower part of the untilit strikes the bundle of Furthermore, I provide around the inner orconcave face of the semi circular guide which lies in the same plane andin the path of the holding-arms. Said curved track forms a ca having anenlarged upper extremity 3 with a convex The extremity of the lever-arm21 is armed with an antifriction-roll, which traveling upon the convexsurface forming the entering portion of track 34 forces. the arm backand closes the gate 19, as shown particularly in Fig. 1, and,furthermore, it will force through the spring 23 the macaroni into acompact mass, the spring, however, taking up excess pressure, so thatthe stock will not be crushed or broken. Holding the macaroni as thusdescribed, the arms carry it against the saws 6, and after leaving saidrotation said arms discharge the sawed macaroni, as will be nextdescribed.

- A box or tray 35 is set beneath the arms and the track 34 isterminated at such a point that as the lever-arm 21 runs off said trackthe spiral spring 26 throws the gate 19 wide open, when one length ofthe macaroni will drop in the said box or tray 35. It will be understoodthat since the adjacent bun-- dles of macaroni are separated by only asawslit the box or trays for the different lengths cannot be arranged inline, but must be staggered, and I therefore terminate the tracks atdifferent points, so that each bunch of macaroni will be dropped intoits appropriate box. r

For driving the mechanism described I have shown in the drawingsbelt-pulleys 37 upon the saw-shaft 5 and a short end shaft 36', whichtransmits motion from said saw shaft 5 by means of a worm-and-ge'a'rconnection to the forward shaft 10, A clutch 38 is preferably employedupon this last or holding-arm shaft 10,.so that the feeding of macaronito the saws is under the immediate control of the operator. 7 I

Having thus described the invention, what I claim as new is 1. In amacaroni-cutting machine, the combination of parallel shafts, sawsmounted on one of said shafts, a longitudinal series of the oppositeside walls, a track adapted to engage the outer portion of said gate andclose the same against the power of said spring, and a roller adapted tobe engaged by the inner portion of the gate before said track is reachedto throw the outer portion into position to engage said track. g

2. In a macaroni -sawing machine,'the' combination with a saw, of aholding-arm having an inwardly concave curved extension and a shortersimilarly-curved eXtension opposite the first, a gate pivoted upon saidshorter arm whose extremity is adapted to describe the curve of theinner surface of the opposite extension, a lever-arm pivoted on saidgate, a spring normally holding said lever-arm away from the gate, atrack adapted to engage the outer portion of said gate and close thesame against the power of said spring, and a roller adapted to beengaged by the inner portion of the gate before said track is reached tothrow the outer portion into position to engage said track, and a springnormally holding the gate open, and means for moving the holding-armswith respect to the saw.

3. In a macaroni-sawing machine, a saw,

lever-arm and the pivoted arm and more yielding than the macaroni, and atrack concentric of the shaft to engage the lever-arm of the pivotedarm, to close the holding-arms during part of the rotation.

In testimony that I claim the foregoing I have hereunto set my hand this30th day of 30 December, 1904.
